The current revolution of the manufacturing sector, usually referred to as Industry 4.0, is deeply modifying the traditional production paradigms. The availability of cost-effective sensing and/or computing elements as well as ad-hoc communications protocols are, in fact, making it possible to provide the whole supply chain with a global awareness about the production process. Selecting the most adequate...
In this paper the use of a wearable device is considered in order to evaluate the performance of an athlete during her/his sport activities. The preliminary step consists of recording the motion variables at a sufficiently high sampling rate throughout the experimental campaign. The collected data are then elaborated by a PC-based application to identify the system dynamics and derive some synthetic...
The paper aims at experimentally assessing the metrological performance of a compressive sampling (CS)-based terahertz (THz) imaging system, an emerging technology for carrying out non-destructive tests of materials in order to detect defects and flaws. Differently from systems based on traditional raster scan, the exploitation of CS allows, in fact, obtaining images of interest in a reduced observation...
The paper deals with the problem of designing and implementing an inexpensive wide area sensors network for environmental radiological monitoring. To this aim, the measurement node takes advantage from a low-cost, Linux based, development platform, and some new open-source software tool, which are pushed towards a network-oriented vision of Internet of Things (IoT).
The paper deals with the distributed monitoring of harmonic and interharmonic pollution in electrical power delivery systems. In order to measure the disturbances and to identify the sources in a wide grid, a distributed measurement system with hundreds of measurement nodes has to be adopted. With the aim of obtaining the reduction of realization costs, the authors propose an innovative distributed...
Wireless sensor networks are today more and more widespread. Along with the installation of more and more networks, a number of new standard documents has also been produced to update the regulation concerning data communication between sensors and data collectors. Differently, less attention has been paid to the different modes of powering the local sensors. At present, the energy required for local...
Nowadays, a variety of measurement applications require the acquisition and processing of signals coming from many disseminated sensors. To reduce the cost of the overall measurement process, the above-mentioned tasks are typically performed by devices like microcontrollers, low cost data acquisition systems (DASs), field gate programmable arrays (FPGAs), and so on. This is particularly true when...
